iPhone users who dream of creating their own Rankin/Bass-style stop-motion animated movies have new tools at their disposal, thanks to a major upgrade to Timelapse Pro.

Version 3.0 of the offering from German developer Drahtwerk features a redesigned user interface, and now lets you add DRM-free music from your iPod library to stop-motion movies, then share those movies via Twitter and FTP. The upgrade also adds full support for iOS 4, including the ability to export movies to the camera roll and iTunes' shared folders feature. There's also new support for the iPhone 4's flash, front camera, and Retina display.

The app doesn't just let you take a series of pictures to create stop-motion movies; it adds to the process with an “integrated viewer” that lets you line up your next shot with a previous photograph in order to create a smoother movie. The results can be seen a demo video Drahtwerk created, embedded below.

Timelapse Pro costs $2 and is compatible with any device running iOS 3.0 or later.
